I agree. The mere presence of clones that don't work diminishes the value of the technique. And at the same time, it probably increases the need for tuning as a...

I started playing with HV programming again yesterday. Partially killed one of my t13s. I have an updated circuit with a PNP+NPN (similar to your pFET + NPN setup). Over...

I'm not able to get the "0xAC 0xC0 0 0" to erase the signature page either. I tried 2 t13s (SOIC & DIP), a t85, and a DIP t88 that...

I did a bunch of testing this eve, and got it to work on the 2nd t13 DIP I tried: ``` HSVP fuse resetter 1E 5C 90 5C 7 FF...

> > > Congratulations! So it works, but not with every chip? Did you use a t13 or a t13a? Both t13a, and both with the same date code of...

IGEN Tech makes different versions of the SOLARMAN RS485 wifi logger sticks with firmware adapted for the modbus register set of a particular manufacturer. For example the wifi stick I...

OK, after a lot more experiments, at least with a Pl2303, I found a 1.5K resistor is best: http://nerdralph.blogspot.ca/2013/09/clone-pl-2303hx-usb-to-ttl-serial.html

I wanted to try the CLI (src/commandline). The first build error I encountered was no libusb, so I removed -lusb from the build command. Then I got a bunch of...

Here's the exact build error from running 'make': ``` gcc -std=gnu99 -g -fno-pie -rdynamic -fPIC -Wall -o dwdebug src/dwdebug.c -lusb -ldl In file included from src/system/system.c:2:0, from src/dwdebug.c:3: src/system/SystemUSB.c:92:19: fatal...

usb.h is not in /usr/include on Ubuntu (14 or 16). If you have it on your Ubuntu install, then you likely have installed the package libusb-1.0-0-dev. To find out what...
